DESCRIPTION
     The NIS subsystem allows network management of passwd and group file en-
     tries through the functions getpwent(3) and getgrent(3).  NIS also	pro-
     vides hooks for other client programs, such as amd(8) and
     rpc.bootparamd(8),	that can use NIS maps.

     Password maps in standard YP are insecure,	because	the pw_passwd field is
     accessible	by any user. A common solution to this is to generate a	secure
     map (using	"makedbm -s") which can	only be	accessed by a client bound to
     a privileged port.	 To activate the secure	map, see the appropriate com-
     ment in /var/yp/Makefile.yp.

     The NIS subsystem is conditionally	started	in /etc/rc.  See the
     /etc/rc.conf file for configuration variables.

HISTORY
     The NIS client subsystem was originally written by	Theo de	Raadt to be
     compatible	with Sun's implementation.  The	NIS server suite was origi-
     nally written by Mats O Jansson.

BUGS
     If	ypbind(8) cannot find a	server,	the system behaves the same way	as
     Sun's code: it hangs.

     The `secure map' feature is not compatible	with non-BSD implementations
     as	found e.g. in Solaris.
